    Welcome. I have a UPC routers at some point with a fixed IP address.
    I would like to be able to configure it from outside at any time.
    In settings I enabled the "Remote access" function on port 8443, but unfortunately nothing else - no possibility of getting to the configuration page.
    In the future I want to configure additional RDP ports.
    Router to Connection Box from UPC.

    PS. Can the port set in the configuration be arbitrary, invented by me?

    it's better / more convenient / safer to place a VPN and have access to the entire canon instead of opening single ports.

    Apparently yes, but on the other side I would have to configure the VPN connection with this router on different devices each time. And this is not an option. I do not always use one and the same device.

    As for this IP I still have to make sure, because it turns out that:
    https://pytania.upc.pl/?q=fact_1006822
    ... I can have a variable address. I need to check it thoroughly.

    I am a little surprised by such questions as yours @MarekPPN because what is in the router (what parameters) to configure it so often? For me once configured router should work without looking.

    Maybe the author wants to open ports for different locations, ie where srcip = X? and X = current ip address.

    ConnectBox and a fixed IP address - since when is a fixed IP address for a retailer at UPC?
    It has blocked this option by default, but you can enable it by activating the option in the menu Tools Administrator-Remote Access (and there you select the port), select what you need and Compal will be rested.

    But why ask such questions? There can be many reasons - I will not list them for you.

    There is actually such an option (bookmark) "Remote access" option is enabled on the port j / w, but if the IP address is really changeable then it's okay.

    Sometimes they can IP in UPC (although variables for the retailer) "hold" the same few months, and sometimes they can change IP on a daily basis - the only advice is NEVER turn off Compal from the power - it gives a certain stabilization that until Compal is online they will not change your IP (though you can not be 100% sure here).

    I can reveal that UPC is working on a permanent IP for retailers - I note, WORKS (which obviously does not mean that such an option for the retailer will ever be and probably as in the UPC Biznes option, this service will be additionally payable monthly).

    I checked. The router still has the same IP address, but unfortunately it is not possible to log into its configuration page. I changed the port for 9000 for sure, but it did not help.
    Ping passes without problems.

    And you restarted the box current for 30 seconds?

    Yes. It happens that this router is turned off during the day for a limited time.
    nmap indicates that port 9000 on the given IP address is open, but I still can not jump to the configuration page.

    Often from the GSM network or just from another stationary location.
    Now the router's IP address has changed. I tried to log in to the new address and port 9000, but the problem is the same as above.

Topic summary

✨ The discussion revolves around configuring a UPC Connection Box router for remote access using a fixed IP address and custom ports, specifically port 8443. The user seeks to access the router's configuration page from outside their network but encounters difficulties despite enabling remote access. Responses highlight the importance of confirming whether the router has a public IP address and suggest using a VPN for enhanced security. Users also discuss the variability of UPC's IP addresses, noting that while some users may retain the same IP for months, others may experience frequent changes. The conversation includes troubleshooting steps, such as checking port settings and ensuring the router is powered on, but the user continues to face challenges accessing the configuration page.

FAQ

TL;DR: To reach a UPC Connect Box remotely, enable Remote Access, set a port, and reboot for 30 seconds; “restart the box for 30 seconds?” 30 sec is the key stat. [Elektroda, KOCUREK1970, post #16822438]

Why it matters: This FAQ helps home users fix remote admin access and choose safer alternatives to opening RDP ports.

Quick Facts

How do I enable remote access on a UPC Connect Box?

Open the UI, go to Tools > Administrator > Remote Access. Enable it and choose a management port. Save settings. Test from an external network. How-To: 1. Enable Remote Access. 2. Set a port, apply. 3. From mobile data, visit https://your-public-IP:port. [Elektroda, KOCUREK1970, post #16805300]

Why can’t I reach the admin page even when a scan shows the port open?

An open TCP port does not guarantee the web UI will load. Application-level access can still be restricted or unresponsive. Users reported nmap showing port 9000 open while the login page failed. Treat this as a service-layer block or policy issue. [Elektroda, MarekPPN, post #16843177]

Does UPC retail offer a fixed public IP on Connect Box?

Forum experience indicates retail lines use dynamic IPs. Addresses might stay unchanged for months or rotate daily. Keeping the box powered can reduce changes, but it is not guaranteed. A paid static IP exists in business tiers, not retail. [Elektroda, KOCUREK1970, post #16809507]

Will my IP change if I power-cycle the router?

Yes, power-cycling can trigger a new lease and change your public IP. Some users keep the box on to maintain stability. This is not assured, and addresses can still change. Plan remote access accordingly. [Elektroda, KOCUREK1970, post #16809507]

Can I pick any custom remote management port like 8443 or 9000?

Yes. Enable Remote Access and select your preferred port in the Connect Box menu. Users tested ports 8443 and 9000 for HTTPS-style access. Remember to allow the chosen port through any upstream filters. [Elektroda, KOCUREK1970, post #16805300]

Is exposing RDP ports a good idea, or should I use a VPN?

Avoid exposing RDP. “It’s better / more convenient / safer to place a VPN and have access to the entire [network].” If you must use RDP, restrict source IPs and monitor logs. [Elektroda, bogiebog, post #16804881]

What is RDP?

RDP is Microsoft’s Remote Desktop Protocol. It lets you control a Windows machine remotely over TCP. Administrators often tunnel RDP through VPNs instead of exposing it online. Port-forwarding alone increases risk. [Elektroda, bogiebog, post #16804881]

Where do I check IPv6 lease time and expiry on the Connect Box?

Log into the router UI. Go to Administrative tools > Information. You will see IPv6 lease time and the exact expiry value. This helps diagnose renewal-related disconnects. [Elektroda, Roger0, post #17222713]

From where should I test remote access?

Test from outside your LAN. Use mobile data or another fixed connection. The goal is to hit the WAN interface, not the internal address. This avoids NAT loopback confusion. [Elektroda, KOCUREK1970, post #16843428]

After changing the remote-access port, do I need to reboot?

Yes. Reboot to apply and clear stale states. “Restart the box for 30 seconds” is reliable advice. That 30-second power-off can refresh leases and services. [Elektroda, KOCUREK1970, post #16822438]

Why does ping work but the web UI still fails?

ICMP ping checks reachability, not service health. HTTP(S) for the admin UI may be filtered or disabled from WAN. Users observed pings succeed while the login page failed. [Elektroda, MarekPPN, post #16822328]

Is it safe to expose the router’s admin interface to the internet?

No. Public admin pages invite brute-force attempts. Use a VPN or limit source IPs if exposure is unavoidable. Disable WAN admin when not needed. [Elektroda, bogiebog, post #16804881]

What if my public IP keeps changing and I lose access?

Expect changes on retail service. Track the current IP before travel, or consider dynamic DNS on your gateway or host. Plan for periodic updates. [Elektroda, MarekPPN, post #16804911]

Can I rely on remote admin daily, or should I automate access?

Because IPs can rotate daily, automate discovery. Schedule checks and alerts for address changes, or avoid WAN admin entirely. Prefer a VPN entry point. [Elektroda, KOCUREK1970, post #16809507]
